Quoted from dleasman:NEED HELP!
On power up, I am getting a "OPTO TROUGH BAD" message. I do not want to panic, and assume it's my Opto 7 board.
Here's what I have done:
I tested the switches in test mode, as I stated above
I re-seated all of the connectors
I removed the ir transmitter board from the trough and viewed the ir emitters through my phone, using the camera
I used the test mode to determine if the opto switches are all working
Here's what I know:
I get the error above on power up, and the machine does not function
I first got the error, but it started working again, then died, then worked, now it does not work at all.
The red led is lit on the opto controller board (hanging vertical under the left corner of the playfield)
In my switch tests, it is changing the states for ball 1 through ball 5 from closed to open, as I drop in each ball.
Switch 36 is always open (should normall be closed according to manual)
Viewing the ir emitters through my phone shows they are all working
Flipper buttons work, and register in test mode
My theory:
I believe that switch 36 "ball stack" should be closed.
I suspect that the 6th opto switch on the trough, which is interrupted as the ball gets pushed up the plunger, is not working.
If the above is true, I have already learned that the emitter is working, so the receiving diode is probably bad, or a bad solder broken loose by vibration, or possible it is not aimed properly.
What I need from YOU (the group):
Since I am not clear on what "normal behavior" is for these opto sensors...
Can someone please go into switch test mode, so you can see the matrix, go to switch 36, and see if it is open or closed. Then, either kick a ball up, or stick a finger down there to see if the state of 36 changes.
Also, if you have any other ideas, theories, or things I can try, please, please let me know.
Attached is an image from the manual, showing the photo sensors (a mirror of the ir emitters). I suspect sensor Q1 is bad (upper left corner of image).
Any and all help appreciated. Thanks in advance.
